I have a clean install of macOS High Sierra with APFS Encrypted file partition. During install I checked the "decrypt at login" option, but each have a different password. I now want to change my APFS password but I haven't been abled to:
- "change password" is greyed out in the Disk Utility for my APFS volume.
diskutil apfs changePassphrase ...returned an error saying it can't do it.
Any idea how I can do that?
P.S. I also have FileVault turned on, with the same password as my login (so different from the APFS Encryption).
